TYPEWRITEE CABINET.

Specification of Letters Patent.

Patented Jan. 31, 1922.

To all whom it may concern:

Be it known that I, BENJAMIN P. Fon'rm, a citizen of the United States, residing in Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Typewriter Cabinets, of which the following is a specification.

This invention relates to improvements in noise-deadening casings or enclosures for typewriters or similar machines, which, in their normal operation, produce suflicient noise to be a source of objection. As herein disclosed, it comprises a noise-insulating casing to enclose the noise-producing parts of the machine while leaving the keys and other operating members accessible to the operative. A. sound-deadening pad or mat is also provided to insulate the machine from the table or support upon which it rests. The enclosure may be provided with openings through which work-sheets, or other material, to be typed or otherwise operated upon by the enclosed machine, may be inserted, and by means of which the margin stops and other parts of the same may be adjusted, and such openings may be provided with sound-proof doors normally closing the same.

As herein disclosed, the invention includes a truck mounted upon the upper outside surface of the casing for movement in a direction parallel to that of the letter-spacing carriage of the typewriter. Thistruck is connected by means of a flexible band, passing over pulleys secured to the casing, to the usual line-spacing and carriage-return lever. of the typewriter. The truck is provided with afinger-piece by which it may be moved, and the connection is such that a movement of the finger-piece from left to right will cause a line-spacing of the platen and a return movement of the letter-spacing carriage. This attachment has the marked advantage that it will not be likely to confuse the operative, since the line-spacing of the platen and return of the letter-spacing carriage is accomplished by a movement of the. aforesaid finger-piece which is in no sense different from the movement of the usual typewriter line-spacing and carriage-return lever for the same purpose.

As herein disclosed, there are provided two transparent panels or windows, one at per window. 6

There may also be provided a paper-guide or deflector, which may be attached to the inner upper surface ofthe casing, and have such form as to cause the typed end of the work-sheet to be moved rearwardly as it leaves the platen, and thus prevent it from falling forward so as to intercept the line of vision between the window in the front of the casing and the printing line. This guide or deflector may be secured to the rear portion of the door at the top of the casing, provided for the purpose of rendering access to the machine and for the insertion of work-sheets. The guide or deflector, when so placed, may also serve as a means for guiding the leading end of the typed work-sheet to a position facilitating its removal from the machine through said door when the typing has been completed.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a perspective view of a typewriter with my improved sound-deadening casing applied thereto.

Figure 2 is a section of the same from front to rear, the typewriting machine being indicated in broken lines. in this View, doors through which access may he had to the enclosed machine are indicated in their open positions by dot-and-dash lines.

Figure 3 is a perspective view of portions of the typewriter and its casing illustrated in Figure 1, but viewed from a different angle, parts being broken away for the sake of 100 clearness.

As herein disclosed, the typewriting machine, designated generally by the reference character 1, is illustrated as being supported upon a sound-deadening pad or mat 2, to 105 other appropriate material, and which may 11 likewise rest upon the sound-deadening pad 2. An opening is provided in the casing 4 through which may protrude the front portion of the typewriter, including the number and alphabet keys 5, by which 1S operated the mechanism through which types 6 are moved to the printing point of a platen 7.

Openings-are also provided through which may protrude the line lock-release key 8 and the bichrom'e-ribbon-shift key 9.

For the purpose of rendering the aforesaid casing 4 soundproof, 1t may be provided with a lining 10 of felt or othersoundinsulating material; This casing, which has an open bottom for convenience in assembling and disassembling'it relatively to the typewriter may rest upon the pad 2 clear of the machine frame, and may be provided with overhanging extending portions 11 to provide for the endwise travel of the usual letter-spacing carriage 12 in which is mounted the platen 7 of'the typewriter. Thebody of the casing may set down in the well usually provided in the typewriter desk, and these portions 11 may extend above the top of the desk.

To provide for the return of the typewriter carriage after it has reached the end of aline, in the course of typing a worksheet, there is provided a finger-piece 13 mounted on a truck 14 and connected with the usual line-spacing and carriage-return lever 16 by means of a flexible band or strip 17. The line-spacing lever 16 is provided with the usual arm- 18 for bringing a pawl 19 into' engagement with a ratchetwheel 20, so as to impart a line-spacing rotation to the platen at each movement of the line-spacing lever 16.

The truck 14, carrying finger-piece 18, is mounted'on rollers 21 adapted for movement in the same direction as the typewriter carriage in channels 22in a track-bar or guideway 23 secured by means of supports 24 to the exterior upper surface of the casing 4. Stop pins 25 are provided to limit the movement of the truck 14 to the right and left, respectively. One end of the flexible band or strip 17 is attached at 26 to the truck 14. From this point, the bandpasses over a pulley 27 mounted on the outside of the casing 4 at the left end thereof. After passing over this pulley 27, the band 17 passes'through a slot 28 in the casin thence across to the pulley 29n1ouuted within the same. From the pulley 29, the band 17 is carried to the linesp'a-cing .and carriage-return lever 16 to which it may be connected by a loop 3O, so as to be readily attachable and detachable at will. Said finger-piece 13 projects at the front of the casing in position to be grasped by the operatorfand is connected, as explained, to effect both a line-spacing operation' and the return of the carriage, and trav els in the same direction as the carriage and to the same extent. 7

To provide for the insertion of 7 worksheets or other material to be typed or worked upon b the enclosed machine, without removing t e'casing 4, there may be provided an opening 31 normall closed by a door 32 hinged at 33, and having a knob 34, so as to be readily swung from its closed po-' sition, as indicated in full lines in Figure 2, to its open positiomas indicated in dot-anddash lines in the same figure. To prevent the leakage of soundbetween the door and the adjacent portions of the casing, the margins of the door may be providedwith strips of soft rubber 36. The door itself may be-lined with felt or sound-deadening material .37, similar to the lining of the body of the cusi o provide for the setting of thc margin stops 38 of the typewriter, there may be provided a second opening 39 normally closed by a door 40 of a construction similar to the door 32. This door 40may be normally held in its closed springs 41', and may be provided with a knob 42 to facilitate the opening and closing thereof.

Both of the'door's 32 and 40 may be provided with transparent panels or windows 43, the window in the door 32 being for the purpose of admitting light to illuminate parts of the enclosed machine, such as the letter-scale and its index as well as the typed portion of the work-sheet above the printing 1 line. The window in the door 40 provides means for observing the above-mentioned parts, thus'illuminated by the window in the door 32. These two win ows thus cooperate to permit constant inspection of the-subj ectmatter being typed upon the work-sheet without opening the doors or removing the casing from the machine.

To prevent the worksheet 44 from-turn- .ing forward, as itis being typed, so as to, I

fall between the window 43 and the printing line, and thus prevent the observation of the portion of the sheet being typed, there may be provided a deflector or paperguide 45. This deflector may to the inner side of the door 32 at a point near the rear thereof, and said deflector may be curved forwardly and downwardly in a form such as to guide the typed part of the worksheet upwardly and rcarwardly in a direction away from the window 43. This guide is also effective to retain the typed end of the work-sheet in a position convenient for the removal of the sheet from the machine on opening the door 32. 4 In order that the casing 4 me be readily applied to, or removed from, the machine, the bichrome-ribbon-shift lrey 9 may be de tachably secured to its shaft 46 by means of a set-screw 47, so that the shaft may be 130 position by retaining 90 conveniently be attached 115 l shaft by means of the set-screw.

thrust through an opening in the casing 4 and the keys subsequently secured to the In like manner, the lock-release key 8 may be passed through an opening 48 in the casing 4.

Variations may be resorted to within the scope of the invention, and portions of the im )rovements may be used without others.
